General Safety & Care Information

1 General Safety & Care Information

1.1 WhoCanUseThisEquipment?● This equipment must only be used by people suitably trained in the use of pipe and cable

locators

1.2 Work-siteSafety

● Use your companies, or other applicable safety code and rules when using this equipment.

● Unless having the required authorization, license and appropriate training – do NOT make

connections to any pipe, cable or conductor.

● Do NOT use this equipment in explosive areas – such as in the presence of flammable liquids,

gases, heavy dust.

● Do NOT directly connect this equipment to cables or pipes that have a potential difference to

ground of greater than 35V AC.

1.3 EquipmentSafety

● Do NOT open the enclosures (housings) of either the transmitter or receiver.

● Place the ground stake firmly in the ground before connecting the cable from the transmitter.

● Do NOT hold any uninsulated portion of the Connection leads & Clips when the transmitter is

switched on.

1.4 BatteriesandEnvironmentalSafety

Vivax-Metrotech products use four types of batteries:

● Alkaline batteries

● Ni-MH (Nickel Metal Hydride) – rechargeable

● Lithium Ion batteries – rechargeable

● Lithium metal batteries – (small non rechargeable button cells for “clock” applications)

1.4.1 AlkalineBatteries

● When replacing the alkaline batteries – use only the size and type specified – do NOT mix

battery types (rechargeable and alkaline).

● Do NOT mix partially discharged and fully charged cells in the same battery pack – do NOT

mix old with new.

● Never attempt to charge alkaline batteries.

of 62

1.4.2 RechargeableBatteriesNickelMetalHydrideand/orLithiumIon● When using rechargeable batteries, use only the correct charging device supplied or specified

by the manufacturer. The battery pack or the battery charger will contain circuitry to manage

the charging process – other chargers (even if they have the same connector, polarity, voltage

& current rating will not have the same control circuitry and can cause damage to the product,

overheating, and in extreme cases fire or harm to the individual.

● DONOT assume that if the plug fits it is the correct charger – a charger with the correct part

number MUST be used – just because it is a Vivax-Metrotech charger and the plug fits does

NOT mean it is the correct charger.

● Before using for the first time, charge rechargeable batteries for 6 hours. If at any time the

rechargeable batteries do NOT last as long as anticipated – discharge fully and then charge for

6 hours.

● Care should be taken when charging batteries – NEVER repeatedly recharge batteries (or turn

power off & on) without using the instrument. If used with an inverter in a vehicle – charge

the product then unplug the charger and do NOT charge again until the rechargeable batteries

have been used for at least ten minutes. Failure to do this could result in the overcharging of

the battery which will shorten the life of the battery, and could in some circumstances cause

overheating or fire.

● If ever the product becomes hot during the charging process IMMEDIATELY unplug the charger

and use the rechargeable batteries for at least 10 minutes before recharging. If this reoccurs

the next time the unit is charged – return immediately to Vivax-Metrotech for repair.

● Lithium Ion Batteries – some products use Lithium Ion batteries – the requirements for

marking and transportation are still developing. Please contact Vivax-Metrotech before shipping

products containing lithium ion batteries or lithium ion battery packs on their own for any “special

instructions”.

● Do NOT charge batteries for prolonged periods of time without using the locator for at least 10

mins. Charging for prolonged period of time could overcharge the battery, reduce the battery

life and in extreme circumstances cause damage to the locator and fire.

1.4.3 LithiumMetalBatteries(nonrechargeable)

● Commonly known as “button cells” these are small – non rechargeable batteries used to power

internal “clocks” within some units (similar to computers). Generally they have a life of 3 -5 years.

● Under no circumstances should any attempt be made to charge these batteries.

● Dispose of to your company’s work practice/environmental standards, the prevailing laws, or

recognized best practice. Always dispose of batteries responsibly.


Page � of 62

1.4.4 GeneralRulesregardingdisposalofbatteries

● NEVER disassemble a battery, or battery pack.

● Never dispose of in a fire or water.

● Dispose of batteries in accordance with your Company’s work practice/environmental

standards, the prevailing laws, or recognized best practice. Always dispose of batteries

responsibly.

1.4.5 TransportationofLithiumIonandLithiumMetalBatteries

● The Lithium ion and Lithium metal batteries used in Vivax-Metrotech products meet the required

safety standards and include the designated protection circuitry.

• Recent regulation changes require that when batteries with Lithium Ion and Lithium metal

batteries are transported the packaging MUST included specified warning labels. Please

contactVivax-MetrotechCustomerService(USA1-800-446-3392– international

+1-408-734-1400 (USA Pacific Time Zone) for more details.

• Regulations have also changed regarding the shipping of spare battery packs (battery packs

that are not inside a product). There are limitations on the weight of the package, and the

packaging must be marked with the appropriate warning labels. PleasecontactVivax-

Page � of 62


1.6 CareWhenInterpretingtheInformationProvidedbytheLocator

• Like all locators – this instrument is locating, and providing depth and current readings based

on electromagnetic signals that radiate from the buried cable or pipe. In most cases these

signals will enable the locator to pinpoint both position depth and current correctly.

• BEWARE – in some cases other factors will distort electromagnetic fields radiating from cable

or pipe being located, resulting in incorrect information.

• Always locate responsibly, and use information learned during your training to interpret the

information provided by the locator.

• Do NOT provide information regarding depth of cable or pipe to anyone unless authorized to

do so by your company.

• REMEMBER that depth measurements are to the center of the electromagnetic field or pipe –

In the case of pipes this may be significantly deeper than the top of the pipe.

3.3 LocatingMode(Response)

The vLocPro receiver has four antennas, and these can be toggled through different configurations

(modes) to provide different responses to the signals radiating from the buried pipes and cables.

The modes are:

The vLocPro is a Precision Location System designed to meet the needs of Utility Companies and

their contractors. The following describes the features and use of the Receiver:

Compass Line

Direction Indicator

Compass Line

Direction Indicator

This uses the two horizontal antennas and provides a “Peak”

or maximum signal response over the center of the radiated

signal from the buried line. The compass line direction

indicator shows the direction of the cable (available in Active

modes). The color of the compass changed from clear to blue

when the receiver is in line with the buried line.

This is the most accurate of the locating modes as both

antennas are used to provide a clearly identifiable “Peak”. In

3.3.2 BroadPeakMode

This uses a single horizontal antenna and provides a “Peak”

or maximum signal response over the center of the radiated

signal from the buried line. The compass line direction

indicator shows the direction of the cable (available in Active

modes). The color of the compass changed from clear to blue

when the receiver is in line with the buried line.

Pushbutton Icon

Pushbutton Icon

3.3.1 PeakResponseMode

the “Peak” mode, a “Peak” signal indicator helps to clarify the position of the “Peak”. This shows

the last “Peak” located for a few seconds, enabling the user to return to that position quickly.

This is less accurate than the twin horizontal antenna “Peak” mode – but is useful if the buried

line is particularly deep. For pinpointing the line, the “Peak” mode should be used.

3 vLocPro Receiver

Page �� of 62

3 vLocPro Receiver

3.3.3 NullMode

3.3.4 SondeMode

This uses vertical antennas and provides a minimum or “Null”

response over the center of the radiated signal from the

buried line. The compass line direction indicator shows the

direction of the cable (available in Active modes). The color of

the compass changed from clear to blue when the receiver is

in line with the buried line.

Pushbutton Icon

Sonde mode uses the antennas in a “Peak” configuration. An ICON on the display indicates if the

receiver is in Sonde mode.

A Sonde is a small transmitting coil that is powered by its own internal battery, or by an external

transmitter.

Due to its construction, a Sonde gives a different “Peak” pattern – when locating along the

direction of the Sonde – instead of the usual single “Peak”, the Sonde provides three distinct

peaks – a small “Peak” – a large “Peak” – a small “Peak”. The Sonde is located under the center

of the large “Peak” when located across the direction of the Sonde and it gives the conventional

peak response. Note that the Compass Line Indicator points across the line of the Sonde when

directly over it and the color of the compass change from clear to blue.

Pushbutton

Compass Line

Direction Indicator

Some users prefer the null response; it works well in uncongested areas, but is more prone to

inaccuracies due to distortion of the radiated signal in congested areas.

Left/right indication arrows are also displayed when in “Null” mode. The arrows indicate the

direction to move the receiver to locate the position of the buried line.

Icon

Compass

Line

Direction

Indicator

Page �2 of 62

The vLocPro receiver must be used in a different orientation when locating a Sonde – due to the

way the signal from the Sonde radiates. With the front of the receiver pointing across suspected

direction of the Sonde – pinpoint forward and backward (across the Sonde) and then move along

the line of the Sonde until the maximum peak is located (in other words rotate the receiver 90

degrees from the orientation normally used when locating pipes and cables).

A Sonde is typically used for locating non metallic pipes or ducts, and the camera end of a sewer

inspection camera. Low frequency versions (512 Hz/640 Hz) can transmit through some metallic

pipes such as cast iron pipes – which are why they are frequently used with sewer inspection

cameras.

For using the compass feature to locate Sondes, please refer to 7.1.3.

3.4 Display

These responses are shown on the display as

● Moving Bar graph

● Numeric value & db value

● Directional arrows (with ‘Null’ response)

● A range of different display modes will be available in 2009

3.5 Audio

The visual display is also accompanied by an audio response. The output level (volume) of this

response is set by entering the “Setup menu”. Press and hold “i” pushbutton for two seconds to

enter setup menu. The setup display defaults to volume. Use the “Mode” pushbutton to toggle

through the available options (off – low – med – high). Press the “i” pushbutton again to exit

the setup menu. As the loudspeaker uses a significant amount of power, using lower volume can

make the battery life of the receiver last longer.

The vLocPro receiver is capable of locating a large number of frequencies or frequency

combinations. A list of these frequencies can be accessed using the setup menu. Most of these

frequencies listed – you will never use – the setup menu allows you to select the frequencies you

wish to use regularly. The frequency select pushbutton on the main receiver pad is used to toggle

through the frequencies defined using the setup menu. The operating frequency will be shown at

the lower right side of the display. You can change this selection at any time using the setup menu.

The initial frequencies set at the time the unit is supplied are “Power”, “Radio” and the frequencies

used by the transmitter purchased. See the transmitter section for suggestions of which frequency

is best suited to specific applications.

To select the frequencies you wish to use regularly

– enter the setup menu by pressing and holding the

“i” pushbutton for 2 seconds. Use the “+” and “-” to

select the word “Frequency” – then press the “M” mode

pushbutton to display the list of available frequencies.

The “+” and “-” pushbuttons are used to navigate the list of frequencies. To add a frequency to

the “Frequently used list” press the “M” pushbutton and a dot will appear in the circle alongside

the frequency. To deselect a frequency press the “M” pushbutton and the dot will disappear. Once

your selection is completed press “i” pushbutton once to return to the setup menu, and again to

exit the setup menu.

Up & down pushbuttons are provided to increase or reduce the

sensitivity of the receiver. If the bar graph moves towards the

minimum or maximum a single touch of the opposite pushbutton

returns it to approximately 60% deflection (i.e. if the bar graph

goes towards the minimum – press the “+” pushbutton, to the

maximum press the “-” pushbutton)

Holding down or repeated pushing of the “+” or “-” pushbuttons increments/decrements the gain.

3.8 InformationPushbutton(Depth&Current)

The accuracy of depth and current readings depends on the quality of the radiated signal being

located. If the signal is symmetrical, the depth reading will be accurate to within 5% of the

actual depth. If the signal is distorted, depth readings will be less accurate. When taking depth

measurement, always hold the receiver at 90o to the ground.

3.9 SetupMenu

IMPORTANT

When locating a cable or pipe (“Line”) – the instrument should be in “Peak”

mode and the depth and current measurements should only be taken with

the bottom of the receiver standing on the ground and directly in line with

the target line.

IMPORTANT

When locating a Sonde – set the mode to Sonde - then the instrument will

automatically be in “Peak” configuration. Depth measurements should

only be taken with the bottom of the receiver standing on the ground and

at ninety degrees to the Sonde.

Page �� of 62

3 vLocPro Receiver

The receiver has two battery packs.

● External alkaline battery pack. Icon A indicates the status of the external battery pack.

● Internal rechargeable batteries. Icon B indicates the status of the internal battery pack.

The unit will operate from the internal batteries until they have no charges left. The unit will then

automatically switch over to the external alkaline batteries when this occurs.

The receiver has an internal rechargeable battery – this will provide the power to the unit unless

you connect an alkaline battery pack. This allows the user to benefit from using rechargeable

batteries, but enables the use of alkaline batteries if for any reason the rechargeable battery lacks

charge.

4.1 Introduction

The vLocML is a variant of the vLoc locator. It can be identified by the loop antenna attached to the base

of the locator tube. The purpose of the loop antenna is to energize passive markers buried above non

metallic services or points of interest.

Markers can be supplied in many sizes or shapes but the most commonly used marker is the ball marker.

This has a range of over 1.5m. Markers operate over a range of frequencies. Different frequency markers

are used to identify different services and are identified by color. The industry standard colors are listed

below:

5.1 Transmitter’sOverview

The vLocPro transmitter is a rugged portable transmitter powered by alkaline “D” cells or Ni-MH

(Nickel Metal Hydride) rechargeable batteries. The following describes the features and uses of

the transmitter.

5.2 TransmittingModes

The transmitter has three transmitting modes, which are selected automatically.

5.2.1 InductionMode – this uses an internal antenna to induce a locating frequency

onto the target pipe or cable (line). “Induction” mode is automatically selected if no connection

accessories are plugged into the “output socket”. An icon indicating “Induction” mode shows on

the display. The icon flashes when the transmitter is transmitting. In order to generate successful

induction, the transmitter should be positioned over and with the handle in line with the target

line.

“Induction” mode is generally used when no access is available to make a direct connection, or

a clamp connection. When using induction it is very likely that the signal being induced onto the

target line will also be induced onto other lines in the area, and onto above ground features such

as wire fences. This can influence the accuracy of the location, depth and current measurements.

“Induction” mode is also the least efficient way of applying the transmitting signal to the target

line. The distance located with “Induction” mode is generally much less than that achieved with

a direct connection or clamp connection. “Induction” mode generally works better in higher

frequencies, 33 kHz, 65 kHz and either 83.1kHz or 200kHz (depending on region). The advantage

of induction is that no access is required to “connect” the transmitter, making it a very quick

process. The antennas on the transmitter are tuned to induce specific frequencies or range of

frequencies. Therefore only a limited number of frequencies can be selected in “Induction” mode.

5.2.2 DirectConnectionMode– By plugging in a connection lead to the output

socket, “Direct connection” mode is selected. An icon confirming this is shown on the display.

The icon flashes when the transmitter is transmitting. The direct connection lead consists of two

cables, one (red clip) must be connected to the conductor being located, the other (black clip) to

a suitable ground (a ground stake is provided with the transmitter). An auxiliary ground lead is

also supplied. If the auxiliary ground lead is used, the ground clip of the connection lead (black

clip) is attached to one end of the auxiliary ground lead.

FUSE

Note:

For accurate location and depth measurement the locator receiver should

be used about 50 feet/20 meters away from the transmitter.

� of 62

Wherever a direct connection can be safely made without the risk of injury, damage to customer’s

plant, or the transmitter, it is the best way of applying the transmitter’s signal.

The coupling of the transmitted signal to other pipes and cables in the area will be much less than

with induction, although where commonly bonded systems are encountered – coupling cannot be

avoided.

The positioning of the ground connection can also influence the degree of coupling experienced.

Ground connections generally should not be made to other pipes or cables, or above ground

metallic structures such as wire fences. In general the lower the frequency is, the further the

signal will travel, and the less signal coupling will occur. The most common frequencies used for

direct connection are between 512 Hz/640 Hz and 8 kHz.

Regulations in many countries require that power output is limited above certain frequencies.

The vLocPro enables frequencies below 45 kHz to be transmitted using as much as 10 watts

output, but frequencies over 45 kHz are restricted to 1 watt. Using direct connection and the

higher power at the low frequencies helps significantly in achieving greater location distances.

Direct connections should not be made to cables carrying greater than 35 volts (or as your safety

practices allow). The transmitter is protected (250v fuse) from stray currents that may exist on

the target line.

5.2.3 ClampMode – plugging the signal clamp supplied by Vivax-Metrotech into the

output socket will place the transmitter in “Clamp” mode. An icon confirming this is displayed

on the display. The icon flashes when the transmitter is transmitting. When using the clamp no

ground connection is needed.

FUSE

The clamp again is a precise way to apply the locating signal. It is generally used when access to

the conductor cannot be achieved to make a direct connection (but there is sufficient access to

place the clamp around the cable), or when it is not safe to make a direct connection because the

target cable is carrying electricity.

FUSE


� of 62

WARNING

When applying the clamp to cables that carry electricity – be sure to follow your

company’s safety instructions and procedures. Beware that if applied around a

high voltage cable – that cable may induce a current in the clamp causing it to

snap shut or jump quite dramatically – always apply clamps carefully.

5.2.4 ConnectionBlock

5.2.5 Frequencies&PowerOutput

The transmitter can be programmed on request to transmit almost any locating frequency in “Direct

connection” mode – up to 200 kHz. When purchased the unit is shipped with a standard selection

of frequencies, plus any you have specifically requested.

Standard frequencies are:

● 512 Hz (where electrical systems are 60 Hz) direct connection – 10 watts

● 640 Hz (where electrical systems are 50 Hz) direct connection – 10 watts

● 8 kHz direct connection – 10 watts

● 33 kHz direct connection, and clamp – 10 watts

● 65 kHz direct connection – 1 watt

● 83.1kHz direct connection – 1 watt (depending on region)

● 200 kHz direct connection – 1 watt (depending on region)

● Induction frequencies are 8 kHz, 33 kHz and 65 kHz or alternately 33 kHz, 65 kHz and 200 kHz

(200 kHz is not permitted in some markets)

FUSE

All the connections made to the transmitter

are made at the connection block except that

a USB socket is mounted inside the battery

compartment for programming the transmitter’s

processor.

The connection block consists of:

● Output (XLR) socket – for the direct

connection lead and clamp.

● Charger socket (to allow the retrofitting of a

rechargeable battery pack – the charging

socket is present even if re-chargeable

batteries have not been purchased).

● Transmitter 12V power lead to power (NOT

charge) the transmitter from a vehicle.

● Fuse – this protects the transmitter circuitry

in the event of the transmitter receiving up to

250v incoming on the output leads.

● A beeper is positioned behind the small hole.

When the locator is within range of the marker there will be a sound from the speaker and also

the icon in the centre of the display (5) will start to fill up.

Move the locator forward and back, left and right, until the largest signal is detected. Note the bar graph (1)

will also respond. Use the “+” and “-” pushbuttons to keep the signal on scale. The bar graph should be

As with most manufacturers the clamps and induction antennas are tuned to specific frequencies,

and do not work over a wide range of frequencies. Special winding/tuning can be provided on

request.

Frequencies are selected by pressing the “Frequency” pushbutton which toggles through the

available frequencies for the selection mode. The frequency is automatically selected if you don’t

toggle past it within 2 seconds. The frequency is shown on the display.

The output current is shown in large characters on the display – to increase or reduce the power

output press “+” or “-”. The vertical bar graph at the bottom of the display indicates which of the

four power output steps is being used.

The current being transmitted will be limited by the impedance of the cable, therefore it is not

unusual to increase the output level, but see no increase in the current displayed. This is not a

fault with the transmitter.

The transmitter will always revert to first level output when switched on – this is a power saving

feature – in most circumstances this output level is sufficient, increasing the power will do nothing

but run the batteries down quicker. All other settings remain the same as the last setting used.

6.6 InductionMode

This uses an internal antenna to induce a locating frequency onto the target pipe or cable (Line).

“Induction” mode is automatically selected if no connection accessories are plugged into the

“output socket”. In order to generate successful induction, the transmitter should be positioned

over and in line with the target line.

“Induction” mode is generally used when no access is available to make a direct connection, or

a clamp connection. When using induction it is very likely that the signal being induced onto the

target line will also be induced onto other lines in the area, and onto above ground features such

as wire fences. This can influence the accuracy of the location, depth and current measurements.

“Induction” mode is also the least efficient way of applying the transmitting signal to the target

line. The distance located with “Induction” mode is generally much less than that achieved

with a direct connection or clamp connection. “Induction” mode generally works better in

higher frequencies, 33 kHz, 65 kHz and either 83.1kHz or 200kHz (depending on region). The

advantage of induction is that no access is required to “connect” the transmitter, making it a very

quick process. The antennas on the transmitter are tuned to induce specific frequencies or range

of frequencies. Therefore only a limited number of frequencies can be selected in “Induction” mode.

Note: For accurate location and depth measurement the locator receiver should not be used

within 50 feet/20 meters from the transmitter.

a)b)

The receiver should be kept parallel to the ground – and should not be flipped up at the end of

each pass. See diagram (a).

To establish the direction of the cable – use whatever mode you prefer to locate the line; then

switch to “Peak” mode to confirm the direction. Pinpoint the line – by carefully establishing the

exact “Peak” position. Then (with the base of the receiver on the ground) rotate the receiver

through 90 degrees, as you do this the signal being received will reduce substantially (possibly

disappear). Then rotate the locator until you find the maximum “Peak”. The front of the locator is

again facing in the direction of the buried line. See diagram (b).

7.1.2 Depth&CurrentMeasurement

Pinpoint the exact position of the cables as follows:

a) Locate lateral position of the cable

b) Rotate receiver to confirm the direction of the cable (you will see a null response when the

receiver is intersecting the direction of the cable at 90 degrees)

Using the vLocPro

7.1 UsingtheReceiver

7.1.1 LineLocating–Linelocatingiswhenapipeorcableisbeinglocated.

When line locating, the receiver should be held with the display forward, and then swept to the

left and right across the suspected direction of the buried line. Note the compass line direction

indicator always points in the direction of the line (active in active modes). The compass color

change from clear to blue when the receiver is in line with the buried line.

7 Using the vLocPro

a) b) c)

7.1.3 SondeLocation

This is used for locating a Sonde only. The relevant factor is that instead of locating a pipe or a

cable where the signal radiated out from the cable (see diagram a) – a Sonde is a transmitting

coil and the signal radiates in a different manner (see diagram b).

a) b)

d) Once the position and direction of the cable has been established, stand with the base of the

locator on the ground – with the locator in the absolute “Peak” position (over and in line).

Then press the “i” information pushbutton briefly, the current and depth will be displayed.

Due to this construction, the Sonde gives a different “Peak” pattern (see diagram b) – note that

there are 3 distinct peaks – a small peak – a large peak – a small peak. The Sonde is located

under the center of the “large peak”, when locating across the direction of the Sonde it provides

the conventional peak response. Note also that the Compass Line Indicator points across the line

of the Sonde when the receiver is directly over it and the color of the compass change from clear

to blue.

c) Rotate the receiver back until it is exactly in line with the cable

Page �� of 62

A Sonde is typically used for locating non metallic pipes or ducts, and the camera end of a sewer

inspection camera. Low frequency versions (512Hz/640Hz) can transmit through some metallic

pipes such as cast iron pipes – which is why they are frequently used with sewer inspection

cameras.

The procedure for Depth Measurement is the same as in line location, but must be done in the

Sonde mode. Depth measurements taken from a Sonde in any mode other than Sonde mode will

be inaccurate.

7.1.3.1UsingtheCompassFeaturetoLocateSondes

Switch on the vLocCam. Select the frequency to match the Sonde frequency. Use the mode

pushbutton to select Sonde.

Stand in the approximate vicinity of the Sonde. Press the “+” pushbutton to increase the gain

so that a steady bar graph reading is displayed. If no or very fluctuating bar graph is shown, it

means that the Sonde is not in the expected vicinity. If this is the case pull back the Sonde to a

known position, which may be the point the Sonde enters the pipe, and start the search here.

Rotate the locator until the compass is pointing at 12 o’clock. Walk in the direction of the compass

keeping the compass pointing at 12 o’clock. The locator will lead you in an arc that crosses over

the Sonde. Press the gain pushbuttons to keep the bar graph on scale. The maximum bar graph

indicates the position of the Sonde.

7 Using the vLocPro

Page �� of 62

7 Using the vLocPro

To pinpoint the Sonde, find the peak in both directions.

When over the peak position, the depth is automatically displayed. Press the “i” pushbutton to get

a more precise depth reading.

TIP

Using the compass to locate the Sonde requires free space to walk to the side of the Sonde. If

there is an obstacle such as a wall or vehicle that restricts walking in an arc, the following method

can be used.

1. Position the locator in the approximate vicinity of the Sonde as above.

2. Rotate the locator so that the compass is now pointing at 3 o’clock.

3. Now step to the side keeping the locator pointing in the same direction. The compass will

rotate slightly.

4. Keeps the locator pointing in the same direction and walk forward. The compass will

slowly rotate. When it reaches 12 o’clock follow the compass keeping it at 12 o’clock.

Pinpoint the Sonde as in the first procedure.

7.2 PassiveorActiveLocation

There are two types of location method available with this system, they are:

7.2.1PassiveLocating

Passive locating is locating buried utilities using the electromagnetic signals that exist in the

environment. We group these under two settings:

● Power (P) – these are signals that generally originate from electrical power generation systems.

These are around 50/60 Hz and their associated harmonic.

● Radio (R) – these are signals that are generally originated by low frequency radio transmissions.

These are generally in the range of 16 kHz to 22 kHz.

Passive location is used to search an area to see if buried metallic lines are present (known as

locating to AVOID). It does not help to identify what buried pipe or cable is present, only to

confirm that there is a pipe or cable there. A typical application would be to check an area before

installing a fence post.

Active locating is using a transmitter to apply a very precise frequency to a pipe or cable, and

then using a receiver turned to find the signal being radiated at that precise frequency. Active

location frequencies can be applied by direct connection, clamp or induction.

This receiver provides a wide range of frequencies for active location. Some will be the same as

the frequencies provided by the Vivax-Metrotech’s transmitter, others will be frequencies used in

other manufacturers’ transmitter.

The choice of frequencies when using induction or the clamp is restricted due to the requirement

that these modes be tuned for specific frequencies (or range of frequencies). The full range of

frequencies is available in “Direct connection” mode.

For frequencies below 45 kHz, authorities such as the FCC allow higher power output to be used;

for frequencies of 45 kHz and above, power output for this type of equipment is restricted to 1

watt. Therefore more power is available when lower frequencies are used.

7.3 ApplyingtheTransmitter’sSignal

The transmitter’s signal cable is applied in any one of the three ways:

7.3.1 DirectConnection - this is used on pipes or cables that are not carrying any

electric current. The “Direct connection” mode will be selected automatically when the connection

leads are plugged into the transmitter.

Do NOT plug the connection leads into the transmitter before connecting to the buried line and

fixing the ground stake. Take the ground stake and push firmly into the ground and connect to

it the black connection lead. Connect the red connection lead to the target line after removing

any surface corrosion. To make the signal travel further along the buried line, ensure to place the

ground stake as far away as possible, and at 90 degrees to the line. Where practical avoid having

other buried lines between the ground stake and the target line, this will reduce the chances of

the transmitter signal coupling to another pipe or cable. Do NOT connect the black lead to any

other metallic items that may have an above or below ground structure, or to any other pipes or

cables; connecting to such items would cause signals to radiate from these secondary structures,

which in turn will increases the likelihood of an incorrect locate.

Plug the connection leads into the transmitter switch on and select the desired frequency.

Warning !NEVER make a direct connection to cables carrying electric/current/

voltage

FUSE

For a clamp to work the current induced by the clamp must flow along the buried line. This means

the buried line must have a ground connection at both ends.

Do NOT plug the clamp into the transmitter before applying it to the target line. Open the jaws

of the clamp, place around the target line, close the jaws. Be sure that the jaws of the clamp are

completely closed. After applying the clamp, plug it into the transmitter, switch on and select the

required frequency. Clamps are generally turned to specific frequencies. Your transmitter only

allows frequencies that are compatible with the clamp to be selected.

Please note – at the end of the clamp, and in the area close to the clamps hinge the exposed

end of the clamp laminations can be seen. Any dirt or corrosion on these ends will reduce the

efficiency of the clamp.

7.3.2 Clamp(Coupler) This is used when applying the transmitter signal to cables carrying

electric current, or cables where access to the metallic conductor is not possible, or undesirable.

The “Clamp” mode is selected automatically when the clamp is plugged into the transmitter.

Warning !BE CAREFUL not to hit other buried lines when inserting the ground stake

into the ground. Check using passive location prior to inserting ground

stake. Stop if additional resistance is felt during insertion.

7.3.3 Induction – This is used when no connection via direct connection leads, or coupler

is possible. If no connection leads or clamp are connected to the transmitter, it will automatically

select “Induction” mode.

An induction loop is fitted inside the handle of the transmitter. The transmitter must be placed

over the target cable with the handle over and in line with the target pipe or cable. The induction

loop is tuned to operate at specific frequencies. Only these frequencies can be selected when in

“Induction” mode.

Do NOT place the transmitter on a manhole cover, or any other such metallic object, as that

object will shield or soak up the signal resulting in little of no signal being induced in the target

line.

When using the “Induction” mode to apply a signal to a line, ensure that a minimum distance of

50 feet / 20 meters is maintained. This is because the transmitter will transmit signal through the

air which will interfere with signals from the cable, resulting incorrect information.

Warning!ALWAYS FOLLOW the appropriate safety requirements mandated by

safety legislation, safety practice or your company’s safety procedures

when applying a clamp (coupler) to a cable.

Warning!BEWARE that when placing a clamp around cables carrying high current,

the clamp may vibrate, jump or close violently due to inducted current

from the target cable.FU

7.3.4 Searching(sweeping)anArea

In any given area, it is likely that buried pipes and cables are not parallel to each other, frequently

they will cross the area being searched at a variety of different angles and depths. As the

response of locator antennas is directional, it is important to search the area in the same or

similar pattern as below. This orients the antennas in a way that will locate any signals being

radiate from the buried line. Once a response is found, then trace and pinpoint the line and mark.

Searching an area in this way is generally (but not exclusively) done in the “Peak” mode using

passive locating.

7.3.5 TracingaBuriedLine

Once a buried line is located it is generally necessary, and a good practice, to trace that line for

some distance in both directions. Whenever practical it should be traced to a point that provides

additional confirmation of what type of service is being located (a telephone pedestal, a manhole

cover etc). If tracing a line to which a transmitter signal has been applied, one should trace out

from the transmitter connection point. The receiver should be held level to the ground and rotated

in a small arc across the anticipated route of the buried line. A clear response should be visible on

the display and heard audibly.

7 Using the vLocPro

Page �� of 62

7.3.6 Pinpointing&ConfirmingtheBuriedLine

Marking the exact position of the buried line is generally called pinpointing. Pinpoint the line

before marking its position. Place the receiver in “Peak” mode, pass the blade of the receiver

across path of the cable and identify the peak response on the display and/or audibly.

a) b)

7.3.7 DistortedFields

When locating always be aware that you are locating the signals radiating from the buried line,

and these radiated fields as they are called can be distorted by other lines or electromagnetic

buried lines or metallic features like crash barriers or wire mesh fences. The risk of an inaccurate

location can be reduced further by the following:

● Check to see if the signal is being distorted by other radiated fields. Locate the cable, first in

the “Peak” mode, and then in the null mode. The two locations should indicate that the cable is

in the same place. If they do not, the signal field is distorted and the depth measurement may

be inaccurate.

● Measure the depth of the buried line by pressing “i” pushbutton briefly to measure depth and

current. The depth should be approximately in line with the “as built” plans available. If no

plans are available logic would still help to assess the situation (if you are looking for a CCTV

distribution cable and the depth indicated is 5ft (1.5m) it is probably not your cable). Current

will be displayed at the same time as the depth.

● A depth reading on congested areas of close to bends or tee’s maybe inaccurate due to

distorted fields.

7.3.8 MeasuringDepthandCurrent

● Pinpoint the cable as described in Pinpointing cable, with the receiver in line with and directly

above the buried line – measure the depth (d) by pressing “i” pushbutton briefly. Current will

be displayed at the same time as the depth.

● Be careful when locating in congested areas of close to bends or tee’s, they may be inaccurate

due to distorted fields.

• Measure the current. This is displayed when you briefly press the “i” pushbutton to measure

depth. The signal from the transmitter will attenuate with distance. The further you are away

from the transmitter the less signal will radiate from the buried line. By locating at several

points along the buried line you will identify an approximate rate of signal loss (beware that

where a pipe or cable divides the signal will reduce more rapidly). If the signal at the point you

are pinpointing is different from the trend would suggest – between that, it may not be the

buried line you expect.

Warning!NEVER mechanically dig over the path of a buried pipe or cable. ALWAYS

dig carefully

Distance A to B = Depth (D) Distance (A’ to B’)/2 = Depth (D)

• An alternate method of verifying depth (D) is triangulation which can be done in “Peak (Twin

antenna)” or “Broad Peak (Single antenna)” modes.

7.3.9 SignalDirectionPrecisionIdentification(Available for vLocPro-SD model only)

Some models in the vLoc range of locators contain a feature called “SIGNAL DIRECTION”. This

feature is used to verify if the line being located is the line to which the transmitter has been

connected.

When a transmitter is connected to a target line the signal travels along it and finds the easiest

way to travel back, usually via the ground and ground stake. However, very often the signal will

travel back along adjacent cables or pipes as these can offer an easier route.

7 Using the vLocPro

Page �� of 62

As a result there can be multiple signals radiating from cables and pipes in the area making it

difficult to identify the target line. These return signals are typically traveling in the opposite

direction than the applied signal. The Signal Direction feature identifies which direction the signal

is flowing and hence the target line.

To use the signal direction system:

● Connect the transmitter to the target line using a direct connection only.

● Turn the transmitter and receiver on and set both to :

。SD-USA – if in North America or any territory where the power system is 60Hz.

。SD-EUR – if in Europe or any territory where the power system is 50Hz.

● The receiver may, or may not be flashing the “SD” icon and compass bezel. “

"A flashing icon and bezel indicates that the unit needs to be synchronized with the

transmitter.” Even if the icon is not flashing it is always good practice to synchronize the

system at the beginning of a survey to ensure reliable results and to maximize the distance to

the next synchronization point.

● To synchronize the receiver to the transmitter at the beginning of a survey, pinpoint the line

very close to the transmitter – be sure that it is the correct line. Then, standing facing away

from where the transmitter is attached and press the “i” pushbutton. The unit will now display

the information screen showing the depth of line, signal current and a hand with the “SD”

icon positioned over the return pushbutton. Pressing the return pushbutton will synchronize

the system and return the unit to the locate screen. The top portion of the bezel surrounding

the compass will light and not be flashing indicating the receiver is locked onto the signal. The

system is now synchronized.

● Proceed to locate, trace, pinpoint as required ensuring at all times the top portion of the

compass bezel remains illuminated.

● If at any time top portion of the bezel ceases to be illuminated and the bottom portion of the

When performing a reset, take care to ensure that you have not strayed

from the target line.

There will be a point at which it is not possible to reset and continue.

However beware that if a non target line is commonly bonded to the

target line that line will also appear as being “in Sync” with the target

line.

7.4 UsingtheAccessories

7.4.1 UsingtheLPCSeparationFilter

The LPC separation filter (LPC) is used to safely inject a trace tone to a live cable via a domestic

mains socket, so that the cable can be traced from the premises to the connection in the street. It

is suitable for connecting to voltages between 100V AC and 250V AC.

Method:

Plug the LPC into the output socket of the transmitter. Identify a suitable main socket. If a switch

is fitted to the socket, switch off. Plug in the LPC to the mains socket and then switch back on. Set

the LPC rotary switch to match the two indicator lights. Set the transmitter to the frequency to be

located. (8 kHz or 32 kHz are good frequencies for this application). Set the output to mid range.

NOTE:

If several lines are commonly bonded the Signal Direction will carry

through to the other lines. This is useful for locating multiple line

installations.

WARNING

Both connection ends contain power voltage. Please handle with care.

Page �� of 62

The A-frame accessory is used to detect ground faults on pipes and cables. In the case of pipes,

the faults consist of coating defects. In the case of cables, faults are usually caused by insulation

damage allowing the metallic sheath (or internal conductor) to become in contact with the

ground.

To detect a damaged section, the line should be isolated and have all ground bonding removed.

This will ensure that the ground fault is not masked by deliberate bonding to ground. The A-frame

cannot distinguish between these two situations.

After isolating the line, use the vLocPro transmitter resistance measuring function, or a dedicated

resistance measuring device to confirm that there is a fault to ground. The A-frame will typically

detect faults up to 2 mega ohm and above (depending on the distance from transmitter, soil

conditions etc).

Connect the transmitter to the target line using the red lead. An earth stake needs to be pushed

into the ground and the black cable clipped to it. Try to place the earth stake as far as possible

from the line to be evaluated. This ensures return currents do not distort the results. Switch on

the transmitter and select either FF low or FF high. Use FF high if the line to be surveyed is long

or the fault resistance is high.

7.4.2 UsingtheA-frameinFaultFinding

7 Using the vLocPro

Page �2 of 62

Plug in the A-frame to the receiver accessory socket. When the receiver is switched on, it will

automatically default to the A-frame screen.

Remove the plastic spike covers from the A-frame. Walk along the route of the line placing the

spikes of the A-frame in the ground (with the green leg pointing away from the transmitter

connection point) every two or three paces. If starting near the transmitter, the Arrow on the

display will point away from the transmitter. As the distance from the transmitter increases, the

dBuV reading will reduce and eventually the arrow will fluctuate or disappear all together. This is

because the fault location is further along the line. If the left/right arrows are activated, use them

to ensure the A-frame is positioned over the line and continue placing the A-frame in the ground

every two or three paces. If the left/right arrows are not activated use the “Return” pushbutton

to enter the locate screen allowing the user to confirm the position of the target line. Press the

“Return” pushbutton again to re enter the A-frame mode.

Eventually the A-frame will detect the fault signal and the “Fault Find” arrow will point forwards.

Continue moving forwards, it may be worth reducing the distance between measurements points

as the fault is neared. The dBuV reading will increase as the fault is neared. Maximum reading

will be just before and just after the fault. When over the fault, the dBuV reading will drop and

the arrow will flip backwards indicating that the position of the fault has been passed. Carefully

place the A-frame before and after the fault to pinpoint the position. Repeating this across the

line direction will pinpoint the fault laterally. Where the two lines cross is the fault position.

7.4.3 UsingtheRemoteAntennaUSB

The remote stethoscope antenna can be used to help identify a particular cable on a cable tray or

where cables are bunched together.

Methods:

1. Connect a signal to the cable to be identified. The remote stethoscope functions has an

operational frequency range of 512Hz up to 200kHz, but low frequencies should be a

preference in this application as they are less likely to leak or bleed over to other cables.

TIP

If it is suspected that there is just one fault. Insert the A-frame approximately

one meter from the earth stake. Note the dBuV; this is approximately the

maximum dBuV reading that will be measured over the fault.

WARNING

Always disconnect or isolate cables before making connections to conductors.

Never attach the transmitter to live cables unless authorised. Use the

appropriate accessories.

7 Using the vLocPro

Page �� of 62

2. The best method of signal application when identifying cables is to use the signal clamp.

This is because the signal clamp applies a signal to the target cable and shares an equal

amount with other cross bonded cables.

3. When using the signal clamp, both ends of the target cable should be grounded. Apply

the clamp below the ground point. Applying the clamp above the ground point will

prevent the signal finding the return path through the ground, so is not advised.

4. If this is not possible use a transmitter signal clamp use a direct connection lead to make

an electrical connection to the cable. Removing any cross bonding between cables

prevents the signal travelling along commonly bonded cables.

5. Do not use the Induction method as the signal will appear on all cables in the area of the

transmitter.

6. Connect the remote stethoscope antenna to the accessory input of the Receiver. The

correct settings and user interface will be automatically selected.

7 Using the vLocPro

Page �� of 62

7. Ensure the frequency selected on the vLoc is the same as selected on the transmitter.

8. Place the stethoscope on each of the suspected target cables with the flats of the

antenna in line with the route of the cable.

9. Note the dB reading of each cable. The one with the largest reading is likely to be the

target cable.

10. If necessary adjust the sensitivity of the vLoc so that the signal is within the operating

section of the bar graph. This will help identify the cable if the signal levels are similar

because of cross coupling of the signal.

WARNING

The remote stethoscope antenna is a useful tool to help identify cables.

However, it should not be used as positive identification before an unused

cable is cut. Always follow company procedures when cutting disused or

isolated cables.

TIP

The remote antenna USB stethoscope can be used to identify disused and

isolated cables. This process can be further enhanced if the cable is isolated

and is of a twisted cable construction.

Methods:

1. Connect the transmitter to two of the cores of the cable. At the far end short together

these two conductors making a loop.

2. Set the transmitter to a low frequency such as 640Hz and set the output to maximum.

3. At the point of interest, run the remote stethoscope antenna along the suspected target

cable. If the correct cable is being assessed the signal will increase and decrease in

sympathy with the twist of the two conductors within the cable.

4. If the signal is a steady level and does not rise and fall, this is probably NOT the target

cable.
